Endocardite infecciosa em pequenos animais

Infective endocarditis is a process in which an infection attacks the heart endothelial surface, and is commonly caused by bacterial colonization, which is called bacterial endocarditis. It is a condition rarely found in dogs and cats, and is more prevalent in male dogs of large size. It mainly affects the left side of the heart, affecting the mitral and aortic valves with greater frequency. The circulation of the bacterium in the bloodstream is what gives rise endocarditis, and is caused by any non-aseptic process that serves as a gateway for bacterium in the body, as from a skin lesion, even as an invasive procedure, such as, catheterization and surgery. The ante-mortem diagnosis is difficult because the clinical signs of endocarditis are varied and common to other diseases, summing up the signs of infection (fever, lethargy, weight loss), and presence of heart murmur and may show signs of congestive heart failure. Thus, the diagnosis is most often through autopsy. To arrive at a diagnosis should be used, besides the history and physical examination, some laboratory tests, especially blood cultures and echocardiography. Treatment is accomplished through the use of antibiotics for long period of time, it is very important to follow the results of susceptibility after its outcome is revealed. The prognosis for bacterial endocarditis ranges from guarded to poor, and can be assessed mainly by the echocardiography. There are few studies in veterinary about the bacterial endocarditis, and the majority is case reports

Odontological assistance to Down Syndrome patients having congenital heart malformations

In this study the authors present the frequency and types of congenital heart malformations (CHM) among Down Syndrome (DS) patients emphasizing the prevention of infectious endocarditis (IE) with appropriate antibiotic prophylaxis (ABP). Out of 390 DS patients, 312 (80%) were considered free from any CHM. 78 (20%) presented some CHM; from these 11,54% (n=9) have more than one CHM; ABP to prevent IE was recommended for 41,03% (n=32). Ventricular septal defect was the most frequent CHM (20,51%, n=16). Dentists must know about the patients’ cardiologic diagnosis before a treatment that could cause bleeding, because they have to administer antibiotics to prevent IE. Although some CHM doesn’t need ABP, according to the protocol of the American Heart Association, there are systemic conditions in DS that are relevant to the prescription of antibiotics.

Efeito de produtos químicos sobre a mancha bacteriana (xanthomonas perforans) e na ativação de proteínas relacionadas à patogênese em tomateiro

The present study aims to evaluate the effect of fungicides and antibiotics to control bacterial spot (Xanthomonas perforans) in tomato, and the activation of pathogenesis-related proteins. Hybrid tomato AP 529 was used to assess the severity of disease. The treatments consisted of spraying with acibenzolar-S-methyl, fluazinam, pyraclostrobin, pyraclostrobin + methiran, copper oxychloride, copper oxychloride and mancozeb + oxytetracycline, and inoculated and non-inoculated controls. After three days of treatment, all plants were inoculated with X. perforans (10 6 CFU / mL). Leaf discs were collected for assessment of peroxidase, polyphenol oxidase, β-1,3 glucanase, phenylalanine ammonia lyase and protease. The area under the disease progress curve (AUDPC) was calculated with the data of severity. All treatments had reduced AUDPC compared to the inoculated control. Fungicides acibenzolar-S-methyl, pyraclostrobin, and pyraclostrobin + methiran had more satisfactory results in reducing the severity of bacterial spot on tomato. The products based on pyraclostrobin together with acibenzolar-S-methyl induced enzymatic activities of peroxidase, polyphenoloxidase and β-1,3 glucanase, indicating that these products may be related to the induction of resistance to bacterial spot on tomato plants.
